Peritoneal dialysis is a preferred modality of replacement therapy in children and adolescents with end-stage renal disease waiting for kidney transplantation. Recent development of pediatric swan-neck catheters with cuffs, novel dialysis solutions, and cyclers for automated peritoneal dialysis enabled more flexible prescriptions of dialysis with less complication, and improved patients' activities as well as the dialysis adequacy. Principles and practical issues of chronic peritoneal dialysis in children and adolescents are reviewed and utility of a web-based Korean Pediatric CRF Registry is explained.

Chronic kidney disease (CKD)-mineral and bone disorder (CKD-MBD) is a common complication of CKD, often accompanied by extra-skeletal calcification in adult patients. As increased vascular calcification is predicted to increase cardiovascular mortality and morbidity, the revised Kidney Disease: Improving Global Outcomes guidelines recommend avoiding calcium-containing phosphate chelators. However, extra-skeletal calcification is less commonly noticed in pediatric patients. Here, we report our experience of such a complication in pediatric patients receiving maintenance peritoneal dialysis. Extra-skeletal calcification was noticed at the corneas, pelvic cavity, and soft tissues of the lower leg in 4 out of 32 patients on maintenance peritoneal dialysis. These patients experienced the aggravation of extra-skeletal calcifications during peritoneal dialysis, and 2 of them underwent excisional operations. It is required to monitor extra-skeletal calcifications in children on kidney replacement therapy.

Purpose: The purpose of this study was to develop a standardized education protocol for peritoneal dialysis patients. Methods: First, the demand for education was investigated from the 27 patients on peritoneal dialysis and 16 guardians, and later, the standardized nursing education protocol has been developed through the comprehensive literature review and the critical analysis of the related studies. Contents validity and applicability have been tested through the expert group survey. Results: The standardized peritoneal dialysis nursing education protocol with 9 areas and 20 items has been developed. The content validity for timing and duration, contents, method, and place of education proposed by the protocol were all above than 0.8. In terms of the applicability of the protocol, the experts scored between 4.20 to 4.93 for all items except one. The item on home visit education acquired the lowest applicability score, because there might exist potential restrictions in visiting patient's home. Conclusion: The standardized education protocol developed in this study turned out to be adequate by representing high content validity for all items and the applicability also was high except the item on home visit education. Further researches to test the effects of this education protocol should be done.

Empyema necessitatis is a rare complication of an empyema. Although the incidence is thought to be decreased in the post-antibiotic era, immunocompromised patients such as patients with chronic kidney disease on dialysis are still at a higher risk. A 56-year-old woman on peritoneal dialysis presented with an enlarging mass on the right anterior chest wall. The chest computed tomography scan revealed an empyema necessitatis and the histopathologic findings revealed a granulomatous inflammation with caseation necrosis. The patient was treated with anti-tuberculous medication.

오늘날 말기 신부전 환자에서의 심장수술은 보편화 되는 추세이며, 만성 신부전 환자들의 수가 늘어남에 따라 이들 환자에 대한 적절한 치료법 개발이 필요하게 되었다. 이 환자들에게는 관상동맥질환 뿐만 아니라 판막질환도 드물지 않다. 이들에게 시행되는 복막투석은 체외순환에 다소의 지장은 있을수 있지만 수술 전후에 적절한 대책을 준비한다면 더 이상 심장수술의 걸림돌이 되지 않는다. 저자는 심한 승모판막 폐쇄부전과 만성신부전을 동반한 33세의 무뇨증 여자환자에서 기계판막치환술을 시행하였다. 환자는 수술전에 복막투석을 주기적으로 함으로써 수분 및 전해질 균형을 적절히 유지시켰고, 수술후에도 혈액 생화학적 검사결과를 수시로 예의검토하면서 복막투석을 계속시행함으로써 무사히 회복될 수 있었다.

Purpose: Indoxyl sulfate and p-cresyl sulfate are important protein-bound uremic retention solutes whose levels can be partially reduced by renal replacement therapy. These solutes originate from intestinal bacterial protein fermentation and are associated with cardiovascular outcomes and chronic kidney disease progression. The aims of this study were to investigate the levels of indoxyl sulfate and p-cresyl sulfate as well as the effect of probiotics on reducing the levels of uremic toxins in pediatric patients on dialysis. Methods: We enrolled 20 pediatric patients undergoing chronic dialysis; 16 patients completed the study. The patients underwent a 12-week regimen of VSL#3, a high-concentration probiotic preparation, and the serum levels of indoxyl sulfate and p-cresyl sulfate were measured before treatment and at 4, 8, and 12 weeks after the regimen by using fluorescence liquid chromatography. To assess the normal range of indoxyl sulfate and p-cresyl sulfate we enrolled the 16 children with normal glomerular filtration rate who had visited an outpatient clinic for asymptomatic microscopic hematuria that had been detected by a school screening in August 2011. Results: The baseline serum levels of indoxyl sulfate and p-cresyl sulfate in the patients on chronic dialysis were significantly higher than those in the children with microscopic hematuria. The baseline serum levels of p-cresyl sulfate in the peritoneal dialysis group were significantly higher than those in the hemodialysis group. There were no significant changes in the levels of these uremic solutes after 12-week VSL#3 treatment in the patients on chronic dialysis. Conclusion: The levels of the uremic toxins p-cresyl sulfate and indoxyl sulfate are highly elevated in pediatric patients on dialysis, but there was no significant effect by probiotics on the reduction of uremic toxins in pediatric dialysis patients. Therefore, studies for other medical intervention to reduce uremic toxins are also necessary in pediatric patients on dialysis.

Non-infectious complications of peritoneal dialysis (PD) are relatively less common than infectious complications but are a potentially serious problem in patients on chronic PD. Here, we present a case of a non-infectious complication of PD in a 13-year- old boy on chronic PD who presented with symptoms such as hypertension, edema, dyspnea, and decreased ultrafiltration. Chest and abdominal radiography showed pleural effusion and migration of the PD catheter tip. Laparoscopic PD catheter reposition was performed because PD catheter malfunction was suspected. However, pleural effusion relapsed whenever the dialysate volume increased. To identify peritoneal leakage, computed tomography (CT) peritoneography was performed, and a defect of the peritoneum in the left lower abdomen with contrast leakage to the left rectus and abdominis muscles was observed. He was treated conservatively by transiently decreasing the volume of night intermittent PD and gradually increasing the volume. At the 2-year follow-up visit, the patient had not experienced similar symptoms. Patients on PD who present with refractory or recurrent pleural effusion that does not respond to therapy should be assessed for the presence of infection, catheter malfunction, and pleuroperitoneal communication. Thoracentesis and CT peritoneography are useful for evaluating pleural effusion, and timely examination is important for identifying the defect or fistula.

목 적 : 단일 기관에서 만성복막투석을 시행 받고 있는 소아 환자를 대상으로 후향적 단면연구를 시행하여 복막투석 방법에 따른 투석 결과의 차이가 있는지에 대하여 연구해 보고자 한다. 방 법 : 단일 기관에서 2004년과 2007년 사이에 복막투석을 시행 받았던 환자들 중 투석 후 3개월에서 15개월 사이에 복막투석 적절도에 대한 평가가 이루어졌던 35명의 환자를 대상으로 하였다. 연구 당시 시행하고 있던 복막투석 방법에 따라 CAPD 군, CCPD 군과 NIPD 군으로 환자들을 분류하였고 각각 17명, 13명, 5명의 환자들이 포함되었다. 각 군 사이에 항고혈압제를 복용하고 있는 환자 수, 체중, 신장 및 일반화학 검사와 혈색소 검사를 포함한 혈액 검사 결과의 차이가 있는지 비교 분석하였다. 투석 및 잔여 신기능을 통한 주간 $Kt/V_{urea}$, Ccr과 초여과양 및 소변량에 대한 비교 분석도 시행하였다. 표준 방법을 통한 복막평형검사를 시행하여 개인의 복막 투과성에 대해서도 알아보았다. 결 과 : 각 군 간에 항고혈압제를 복용하고 있는 환자의 비율, 체중과 신장 Z-score의 월간 변화 및 혈액검사 평균 수치의 차이는 유의하지 않았다. CAPD 군과 CCPD 군에서, 복막투석 및 잔여 신기능을 통한 주간 Kt/Vurea, Ccr 및 수분 배설 의 차이는 없었다. NIPD 군의 복막투석을 통한 주간 Ccr이 다른 두 군에서보다 유의하게 낮았지만, 잔여 신기능을 통한 보상으로 총 주간 Ccr에는 차이가 없었다. 복막 평형 검사 결과 저 투과성(low transporter) 및 저 평균 투과성(low average transporter)으로 분류되었던 환자들을 대상으로 비교하였을 때, CAPD를 통한 주간 Ccr이 CCPD를 통한 주간 Ccr 보다 유의하게 높았다. 결 론 : 본 연구의 결과를 토대로, 소아 만성복막투석 환자들에 있어서 투석 방법은 환자의 선호도에 의하여 자유롭게 선택될 수 있어야 할 것을 제안하는 바이다. 또한 초여과의 실패 및 부적절한 투석으로 투석 방법의 변경이 불가피한 상황에서, 복막 평형 검사는 투석 방법 변경이 적절이 이루어질 수 있도록 도와주는 귀중한 정보를 제공해 줄 것이다. 투석 방법 간의 명확한 비교를 위하여 향후 복막염의 빈도, 영양상태 및 장기간의 성장등 다양한 투석 성적을 비교하는 추가 연구가 필요할 것으로 생각된다.

Objectives : We wanted to evaluate the economic value of a pharmaceutical product, Kremezin, for treating patients with chronic renal failure (CRF) by estimating the amount of cost savings due to its effect for delaying the initiation of dialysis treatments. Methods : We defined a conventional treatment for CRF accompanied by Kremezin therapy as 'the treatment group' and only conventional treatment as 'the alternative group.' The types of costs included were direct medical and nonmedical costs and costs of productivity loss. The information on the effect of Kremezin was obtained from the results of earlier clinical studies. Cost information was derived from the administrative data for 20 hemodialysis and 20 peritoneal dialysis patients from one tertiary care hospital, and also from the administrative data of 10 hemodialysis patients from one free-standing dialysis center. Per-capita cost savings resulting from Kremezin therapy were separately estimated for the cases with delay for the onset of hemodialysis and the cases with immediate performance of peritoneal dialysis. By computing the weighted average for the cases of hemodialysis and peritoneal dialysis, the expected per-capita cost savings of a patient with CRF was obtained. Using a discount rate of 5%, future cost savings were converted to the present value. Results : The present value of cumulative cost savings per patient with CRF from the societal perspective would be $18,555,000{\sim}29,410,000$ Won or $72,104,000{\sim}112,523,000$ Won if Kremezin delays the initiation of dialysis by 1 or 4 years. Conclusions : The estimated amount of cost savings resulting from treating CRF patients with Kremezin confirms that its effect for delaying the onset of dialysis treatments has a considerable economic value.
